IMPROVEMENT IN WASH-BOILERS.

Specification ormn g part of Letters Patent No. 3?,902, dated April 15,1873 application filed March 22, 1873.

To all whom it may concern:

Be it known that I, WILLIAM EXNER, of Harpers Ferry, in the county ofJefferson and State of West Virginia, have invented a new and valuableImprovement in Wash-Boilers; and I do hereby declare that the followingis a full, clear, and exact description of the constructionand'operation of the same, reference being had to the annexed drawingmaking a part of this specification, and to the letters and iigures ofreference marked thereon.

Figure l of the drawing is a representation of a plan view of mywash-boiler. Fig. 2 is a sectional view of the same. Fig. 3 is a detailview.

This invention hasrelation to wash-boilers; and it consists in theconstruction and novel arrangement of the parts of the current-washer,the flanched case, and the lid-valve, as hereinalter described.

The main object of this invention is to provide a steam-washer whichwill afford a smooth cavity for the reception of the goods, whereby theywill not be so liable to be torn or perforated in the washin goperation.

In the accompanying drawing, the letter A indicates the boiler-case,which is provided with an external flange or ledge, a., inclined upwardand outward, and extending horizontally around the casing at somedistance below its upper edge. A spout, b, is arranged at one end ofthecasing, designed to lead the water which may overiiow into the ledge ato a suitable receptacle, thus preventing the same from falling on thehot plates of the stove and cracking them. B indicates the lid providedwith fastening-rings c at its ends, which engage with studsd on the endsof the casing. The lid is perforated at e for the passage of superluoussteam, these perforations being arranged near the handle C, and coveredby an angular Valve-plate, h, which is kept in place by a rod, lf,passing from the lid to the handle through a perforation in said valve.D indicates the steamer or current-washer. This consists of anelliptical outer wall, l, designed to lit neatly the inside of theboiler-casing. The spouts and base-chamber 0f this washer are formed bythe intersection with this elliptical wall of the horizontal plane platem,`and the two inclined plane plates n extending from said horizontalplate upward and outward, forming a spacious cavity, U, flaring towardthe ends of the boiler for the reception of the clothes to be washed.The spoutsE E are thus formed wide and taperin g upward. Theperforations c c for the discharge ofthe current of steam and boilingwater upon the clothes are made through. the inner or plane walls n ofthe spouts. At the central portion of the hori- Zontal or base-plate m,on which the goods rest, is made an opening, u, through which the waterpasses from the goods into the chamber below said base-plate. Above thisopening is a raised guard-plate, w, which is supported by arms i.Vindicates a valve located below said opening, a, and provided with aguide-pin, z, extending between two crossbars, s. The current-washer isprovided with handles G, attached to its spouts for the purpose oflifting it out of the boiler-case when desired.

The operation of this boiler is as follows: Water having been pouredinto the base cham ber the clothes or goods are introduced and the lidfastened. Upon the 'formation of steam the water is carried up, andthrough the per- A forationsof the spouts is discharged on the goods,through which it passes down under the gn ard-plate w, and through theopening u to the base-chamber again. The valve Vcloses the opening uintermittently when actuated by strong steam-pressure.

What I claim as my invention, and desire to secure by Letters Patent,is-

The steam-washer, consisting of the casing A and the close fittingcurrent-washer D, having the tapering spouts E, with plane inner walls nextending entirely across the casing, the opening u, and the valve V, asdescribed.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

WILLIAM EXNER.
